اِهْدِنِي لِمَا اخْتُلِفَ فِيهِ مِنَ الْحَقِّ بِإِذْنِكَ إِنَّكَ تَهْدِي مَنْ تَشَاءُ إِلَى صِرَاطٍ مُّسْتَقِيْمٍ

Ihdini limakhtulifa fihi minal-haqqi bi'idhnika innaka tahdi man tasha'u ila siratim mustaqim

حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، وَمُحَمَّدُ بْنُ حَاتِمٍ، وَعَبْدُ بْنُ حُمَيْدٍ، وَأَبُو مَعْنٍ الرَّقَاشِيُّ قَالُوا حَدَّثَنَا عُمَرُ بْنُ يُونُسَ، حَدَّثَنَا عِكْرِمَةُ بْنُ عَمَّارٍ، حَدَّثَنَا يَحْيَى بْنُ أَبِي كَثِيرٍ، حَدَّثَنِي أَبُو سَلَمَةَ، بْنُ عَبْدِ الرَّحْمَنِ بْنِ عَوْفٍ قَالَ سَأَلْتُ عَائِشَةَ أُمَّ الْمُؤْمِنِينَ بِأَىِّ شَىْءٍ كَانَ نَبِيُّ اللَّهِ صلى الله عليه وسلم يَفْتَتِحُ صَلاَتَهُ إِذَا قَامَ مِنَ اللَّيْلِ قَالَتْ كَانَ إِذَا قَامَ مِنَ اللَّيْلِ افْتَتَحَ صَلاَتَهُ " اللَّهُمَّ رَبَّ جِبْرَائِيلَ وَمِيكَائِيلَ وَإِسْرَافِيلَ فَاطِرَ السَّمَوَاتِ وَالأَرْضِ عَالِمَ الْغَيْبِ وَالشَّهَادَةِ أَنْتَ تَحْكُمُ بَيْنَ عِبَادِكَ فِيمَا كَانُوا فِيهِ يَخْتَلِفُونَ اهْدِنِي لِمَا اخْتُلِفَ فِيهِ مِنَ الْحَقِّ بِإِذْنِكَ إِنَّكَ تَهْدِي مَنْ تَشَاءُ إِلَى صِرَاطٍ مُسْتَقِيمٍ " .

Abd al-Rahman b. 'Auf reported: I asked 'A'isha, the mother of the believers, (to tell me) the words with which the Messenger of Allah (ﷺ) commenced the prayer when he got up at night. She said: When he got up at night he would commence his prayer with these words: O Allah, Lord of Gabriel, and Michael, and Israfil, the Creator of the heavens and the earth, Who knowest the unseen and the seen; Thou decidest amongst Thy servants concerning their differences. Guide me with Thy permission in the divergent views (which the people) hold about Truth, for it is Thou Who guidest whom Thou wilt to the Straight Path. [Muslim: 770]
